Kyle considered trying to talk to his mom about this, but realized that was probably a bad idea. For one a preschooler who just woke up in wet training pants doesn't have much credibility. But he also had to consider she was behind this.
She always treated him like he was a little kid and now suddenly he was. And to top it off she looks the same as she did yesterday. Though considering she had him pretty young she was still a normal age to have a preschooler. And he had no idea how she could have done this.
In either case she was likely going to act like he was just making up stories. Until he had anything to prove he's supposed to be older or that she made him younger, he should probably just act like everything was fine for the moment. Which meant acting like a preschooler.
Sighing internally, he grabbed a plastic boat his mom had placed in the tub. Pushing it around making engine noises with his mouth, Kyle did his best not to react as she cleaned his crotch.
